Abstract

Improving the overall performance of the PV cell can play crucial role to the total generated photovoltaic power worldwide. An efficient window layer is essential to check the front surface recombination in the solar cell. In this paper, we explored InGaP window layer for GaAs solar cell and analyzed performance with the help of PC1D simulation software. For this, we have varied thickness and doping level of InGaP window layer and performance of the solar cell has been examined with the help of current-voltage (I-V) characteristics. We also reviewed the effect of temperature on the performance of the solar cell. It has been found that the short circuit current 3.192 A, open circuit voltage 0.8959 V and power conversion efficiency 25.78% of InGaP/GaAs solar cell at window layer thickness 30 nm with doping level 1.00E+17cm3.

Abstract

This work deals the preparation of a new polymer gel electrolyte using an efficient poly (acrylonitrile)-co-poly (butyl acrylate) (PAN-co-PBA) for solid-state DSSCs. Prepared PAN-co-PBA exhibited the superabsorbent behavior as seen the carboxylate group in copolymer. An excellent gelation with iodide couple and high ionic conductivity of 3.86 mS/cm was recorded for PAN-co-PBA gel electrolyte. Fabricated DSSC with 7% PAN-co-PBA attained the highest overall conversion efficiency of ∼5.23% along with high JSC=13.16 mA/cm2, VOC=0.646 V and FF=0.62. Improved DSSC performance might be related to excellent gelation and high ionic conductivity of PAN-co-PBA gel electrolyte, resulting in improving interfacial contact and pore filling.
